Servicing a Brother PS-100 Sewing Machine (Japanese Model)

Older sewing machines in particular are usually very easy to pull apart and service.  I have DIY serviced many different machines in my time. The screws that need taking out of older machines in order to get the covers off are usually easy and obvious to find.  The screws themselves are also usually “normal” flat or Phillips head screws types.  None of the forever changing tamper proof/special tool screw designs we seem to get now.

If you or yours are into sewing and you notice the machine is starting to play up more than it used to, give it a little love and attention.  Just a bit of oil on the internals is a start, but an overall maintenance service does wonders for operation.   Basically, it is not a particularly difficult task to strip the covers off a sewing machine for servicing.  Just make sure the power is off and unplugged, and don’t force the covers if they are not peeling away relatively freely by themselves after all relevant screws have been removed.

The Brother PS-100 Sewing Machine Service

I recently I opened up an Japanese made Brother PS-100 Sewing Machine for maintenance and refurbishment.  The Brother PS-100 machine, although quite an old model now, is still a good machine by all accounts.  This one was a little rattly after being removed from its dust cover and seeing its very first daylight in years.

Sewing machines definitely require a little service and attention after either lot of use, or after being stored for long periods.  This particular machine hadn’t been out of the cupboard for years.  Much of the grease helping the movement of the plastic gears and parts was dry and hardened.  Never a good thing!  Any metal surfaces were also very thirsty for a few drops of oil.

The Brother PS-100 model of sewing machine was a little tricky to open up initially.    Even with all the relevant screws out, the plastic cover would not budge.  It was as though I hadn’t taken any screws out at all.    Once I realized what was going on with the plastic clips running along (the top side of) the bottom cover (see photo below) , it was a cinch.

At the time of writing, there appeared to be relatively little information about the internals of the Brother PS-100 sewing machine model available on the net.

The Service Result

Mountains of fluff and lint were removed from the bobbin area of this machine and the entire internals needed a good vacuuming.  All obvious parts then received a good oil and lube.

It was quite amazing how much quieter and smoother the machine ran afterwards.  I also heard a difference in the number of evil words being used while the usual user sewed afterwards too!

If you happen to be attempting a cleanup of this particular model of machine and have arrived at HomeDIYStuff as a result, I have one main piece of advice for you.  Make sure you fully understand where the bottom plastic clips of the cover are before forcing anything too hard!  These clips could be very easily snapped off with any over zealousness in prizing of the cover halves.  Take care.  May the various following photos of the PS-100 internal parts assist your DIY servicing journey.

Caution: Tricky plastic clips that hold covers fast, even after taking all screws out.
